Core Functionality for Legacy System Integration
The Schneider Electric AS-J890-101 serves as a vital communication bridge in industrial networks. This RIO interface module efficiently connects Modicon 800 series I/O to your existing 984 programmable controllers. As a result, it provides a reliable and high-performance pathway for system modernization and expansion.
Engineered for High-Speed, High-Density Control
Designed for demanding applications, the AS-J890-101 manages substantial data loads with precision. It supports a total I/O capacity of 2048 discrete points, split evenly between inputs and outputs. Furthermore, its swift sub-1ms scan time for 256 points ensures responsive real-time control.
Compact Physical Design with Intuitive Diagnostics
Schneider packaged this robust functionality into a space-efficient form factor. The module requires only 1.5 slots of panel space and provides clear visual diagnostics through multiple LED status indicators. These features simplify installation, monitoring, and troubleshooting processes for maintenance personnel.
